well, afaik, both Jaroslav and I haven't check this soundcard, because
we have no this hardware.
so, perhaps the answer is that no one is working on it yet.

when i write a new driver, it would take

- ca. 1 week if there is an OSS driver,
- ca. 2 weeks if it's a normal PCI (or ISA) device and there is enough
 technical info, and
- more for exotic environment :)

until the first beta release.  a test version may be ealier, though.


recently i wrote a small howto for writing an alsa-driver.  please
check the archive of alsa-devel ml.


ciao,

Takashi
